Abstract (en)
[origin: WO2014153455A1] An optical device in which crosstalk due to scattering is reduced includes an optical port array having at least one optical input for receiving an optical beam and at least one optical output. The input and outputs extend along a common axis. A dispersion element receives the optical beam from the optical input and spatially separates the optical beam into a plurality of wavelength components. A focusing element focuses the plurality of wavelength components and a programmable optical phase modulator receives the focused plurality of wavelength components. The modulator is configured to steer the wavelength components to a selected one of the optical outputs. The programmable optical phase modulator is oriented with respect to the optical port array so that an axis along which the optical beam is steered is non-coincident with the common axis along which the input and outputs extend.
